To all whom t may concern.'

Be it known that I, WILLIAM L. SECHLER, a citizen of theUnited States,residing at Braddock, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inIrojectile-Protectors; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to provide an extremely simple andinexpensive Ayet an efficient and durable device for encompassing theusual copper packing rings of projectiles to guard the same againstinjury during handling and transportation, and with this general objectin view the invention resides in the novel features of construction andunique combinations of parts to be hereinafter fully described andclaimed, the descriptive matter being supplemented by the accompanyingdrawings which constitute a part of this application, and in which,

Figure 1 is a side elevation of a projectile Showing the application ofone of the protectors thereto;

Fig. 2 is an enlarged longitudinal section of the protector applied;

Fig. 3 is a vertical transverse .section on the plane of the line 3 3 ofFig. 1 showing more particularly the construction of the Split laminatedring and the joint for securing the ends thereof together under ordinarycircumstances Fig. 4 is a detail section similar to the upper portion ofFig. 3, but showing the manner in which the joint may be Severed;

Fig. 5 is a duplicate of Fig. 1 with the exception that it illustrates adifferent form of protector;

Fig. 6 is a longitudinal section of tector shown in Fig. 5;

Fig. 7 is a rear end elevation thereof with parts broken away and insection;

Fig. 8 is a detail section similar to the upper portion of Fig. 3showing a slightly different form of construction; and

Fig. 9 is a detail transverse section through main guard ring, showinganother manner in which the same may be constructed.

In the drawings above briefly described, the numeral 1 designates acommon type of the 4proprojectile while 2 has reference to the usual'another'.

copper packing ring at the rear end thereof, said ring being providedwith the usual grooves 3 which are packed with grease before shipment ofthe projectile. It is the object of the present invention to retain thisgrease in the grooves and prevent the entrance of dust and the likethereto as well as to guard the ring 2 against injury during handling ortransportation. To attain these results, the improved protector' may beconstructed in a'number of ways, but its essential features are a maincontinuous guard ring-4 to surround the rear end of the projectile inabutting relation with the rear edge of the ring 2, an auxiliary andsplit guard ring 5 to surround said projectile in contact with the frontedge of the ring 2, and a split flexible collar 6 extending between andsecured to the two rings 4 and 5.

In Figs. 2, 3 and 4, the ring 4 is shown of laminated construction, thelaminations 7, with the exception of the outermost thereof, being in theform of split rings preferably formed of wood fiber with the grain ofcontacting rings running in opposite directions to gain strength.Alternate laminations 7 extend beyond the intervening laminations, asshown clearly in Figs. 3 and 4, so .that practically a tongue and groovejoint is provided between the two ends of the ring 4, this joint beingfree to spring open as indicated in Fig. 4 when the outer lamination 8is severed, if it should be desirable to remove the ring 4 in thismanner. Said lamination 8 is the only one of the series which iscontinuous, the two ends thereof being riveted together by a rivet 9while other rivets 10 extend through the several laminations to securethem together.

The rivets 10 also pass through one edge of the canvas or the like ofwhich the collar 6 is constructed, said edge being interposed betweencertain of the laminations 7 of the guard ring 4 so that the latterprojects both inwardly and outwardly from said collar to more or lessguard the latter when the projectile is being rolled from one point toThe sheet of material from which the collar 6 is formed, is passedaround the auxiliary guard ring 5 and the free edge portion is securedby several rows-of stitching 11 to the inner face of the collar proper,so that an annular hem isprovided in which a circumferentiallycorrugated ring 12 of ,fiber or thelike is located to assist the collarguarding the packing ring 2 against injury.

The auxiliary guard ring 5 is by preference constructed of severallayers or4 laminations of liber, the ends of which are in no way joinedbut are alinedsubstantially with the split 13 of collar A6, a strap 14being provided for normally holding the ends of said v possible, boththe strap 14 and the outermost lamination 8 of the guard ring 4 willfbecut with a knife or other suitable tool, said lamination being severedadjacent the meetlng -ends of the otherlaminations 7 so that the ring 4Will expand to thef position indicated in Fig. 4. The entire protectoris 'thus free to be quickly withdrawn from the projectile.

In Figs. 5, 6, 7 and 8 the construction is substantially the same asthat above described. In these figures, however, the outermostlamination 8 of the main guardv ring 4 is tapered at its ends so as toform a joint which will offer no obstruction to rolling the shell. Inthis type of the invention the material of which the collar 6 is formedis folded around the ring 4 as well as the auxiliary ring 5, 'the outerand inner portions of the folded material being stitched together at 11so that an annular seam`is formed in which one of the rings or bands 12is located.

Another point of dierence between this type of the device and that abovedescribed is that the strap 14 is eliminated in favor of a cord or smallrope 14 passed around the collar 6 adj acentthe ring 5 with its endstied together. This cord may be either untied or cut to permit thedevice to be removed, and .whenever required vthe lamination 8 may besevered so as to permit 'the entire' device to expand as'abovedescribed.

As a modification of the ring 4, it is shown in Fig. 9 as constructed ofa main body 15 of wood, a number of laminations 7 secured in contactwith the inner face of said ring, and an outer lamination 8corresponding to the parts 8 and 8 above described. This form of ringmay be preferable in some instances since it will not only be lessexpensive to manufacture but will be much stronger than ringsconstructed totally' of fiber.

When the improved devices are applied,

j the vmain and auxiliary rings 4 and 5 as well as the collars 6 andrings 12 effectively serve to guard the packing ring 2 against' injuryand prevent the entrance of dust and grit into the grease in the grooves3. The prounderstood that within the scope of the invention as claimed,numerous changes may be made without sacrificing the principaladvantages. y

While I have shown and described the invention as being applied to theprojectile from its rear end which of course is the most practical Way,since it may be done while the projectile is held by a grapple, it willbe understood that the invention maybe applied from the tapered or frontend of the projectile, or used in the position reverse from what isshown in the drawings.
